To investigate the feasibility and the control condition of the conversion of sulfide to sulfur from man-made wastewater ,lab-scale downflow and upflow colorless sulfur bacteria(CSB) biofilm reactor packing with ceramsite was used.
以人工合成含硫化物废水作为进水 ,采用以陶粒为填料、小试规模的逆流式和顺流式好氧CSB(无色硫细菌 )生物膜反应器 ,在常温 ( 1 7℃～2 2℃ )、HRT为 2 6min、进水pH为 7。
A sulfur-zeolite fixed bed reactor was used to remove the nitrite, while autotrophic denitrify bacteria, sulfate reducing bacteria and colorless sulfur bacteria were used to remove nitrate in influent.
本研究针对污水处理厂出水水质的低COD特征,开发出硫/沸石生物固定床,并通过自养反硝化菌、硫酸盐还原菌、无色硫细菌协同去除水中的硝酸盐。
Compared with other methods,the sulfide removal process based on bio-oxidation with colourless sulfur bacteria is no catalyst,no chemical sludge to be disposed,low energy consumption,possible reuse of sulfur and fast process with high removal efficiency.
经过比较 ,由于用无色硫细菌处理废水中的硫化物具有不需催化剂、无化学污泥、低能耗、有可能回收单质硫和快速高效的特点而将成为今后的发展方
Packing with SRB ( Sulphate Reducing Bacteria ) for treating simulative wastewater with sulphate concentration and packing with CSB (Colourless Sulfur Bacteria) for treating s.
本文分别以活性炭、琼脂、及自制的磁性多孔聚苯乙烯微球固定SRB(硫酸盐还原菌)和CSB(无色硫细菌)，在上流式流化床反应器中处理模拟硫酸盐废水和硫化物废水，结果表明：磁性多孔聚苯乙烯微球具磁性、比表面积大、易回收等优点，固定化SRB的SO_4~(2-)去除率高达96％，固定化CSB的硫化物去除率为88。
